FAIL Red The SF module has failed.
Unlit The SF module is not installed or is not
funconing normally.
Line Card LEDs and Control Buons
Each line card has two LEDs—OK and FAIL—on the cra interface that indicates its status. The line card
LEDs are associated with control buons and are located along the boom of the cra interface. You
can turn a line card online or oine by using its control buon on the cra interface. Table 11 on page
34 describes the funcon of the line card LEDs.

Alarm LEDs and Alarm Cuto Buon
Two large alarm LEDs are located at the upper right of the cra interface. The circular LED called major
alarm LED glows to indicate a crical condion that can result in a system shutdown. The triangular LED
called minor alarm LED glows to indicate a less severe condion (warning) that requires monitoring or
maintenance. Both LEDs can be lit simultaneously.
A condion that causes an LED to be lit also acvates the corresponding alarm relay contact on the cra
interface.
